CRC Error on Fortigate

Posted on June 30, 2012

Sometimes the Fortigate devices has problem and they do not want to boot anymore (my experience is 2 from about 50 Boxes). Sometimes we have to buy a new one, but in this case I mention we should not.
The message crc error is a problem that we can solve alone.

What do we have in a Fortigate 50B:

This is definetly an SMB device, I would wonder what happens if the ips and other utm features are enabled and vpn is configured, would it be much more slower?
